Problem with Qt Designer... Help Me...

[Sparkle24]

Hello guys...

I'm using Nokia Qt SDK 1.1.3 with Qt creator 2.3.0...
I wanna use it on linux platform... So I downloaded "Qt_SDK_Lin32_offline_v1_1_3_en.run" and installed on Ubuntu 11.04 '32bit'...
On Microsoft I can add button & other component with Qt designer but on linux I can't add button & any other component with Qt Designer... When I drag & drop a button or toolButton etc on a Rectangle It show me nothing... Only a blank Rectangle... Can anyone tell me how do I fix it ?

Sorry for my poor english...
Please help me guys coz Qt Quick is very important for me...

Go to Help->about plugins and make sure that all plugins are actually loaded.

Hmmm, all I can suggest at this point is upgrading to qtcreator 2.3.1 and perhaps try removing any existing creator settings that could be getting in the way.
